| Test | Interference |
| $(a)$ $2, 4-DNP$ test | Colorued precipitate |
| $(b)$ Iodoform test | Yellow precipitate |
| $(c)$ Azo-dye test | No dye formation |
Compound $‘X’$ is
| Initial Conc. $(A)$ |
Initial Conc. $(B)$ |
Initial rate of |
| $0.1\,M$ | $0.1\,M$ | $1.2 \times 10^{-3}$ |
| $0.1\,M$ | $0.2\,M$ | $1.2 \times 10^{-3}$ |
| $0.2\,M$ | $0.1\,M$ | $2.4 \times 10^{-3}$ |
For the reaction the rate of formation of $C$ will be
$\mathrm{BrO}_{4}^{-} \stackrel{1.82 \mathrm{V}}{\longrightarrow} \mathrm{BrO}_{3}^{-} \stackrel{1.5 \mathrm{V}}{\longrightarrow} \mathrm{HBrO}$$\stackrel{1.0652 \mathrm{V}}{\longrightarrow} \mathrm{Br}_{2} \stackrel{1.595 \mathrm{V}}{\longrightarrow} \mathrm{Br}^{-}$
Then the species undergoing disproportionation is
